Shale shaker for liquid solids separation to Environmental Solution Company

BY gnadmin 3 January 2021 Uncategorized

Recently one set of vibration shaker for liquid solids separation are shipped to environmental service company.

It is consist of 2 mud tanks, each tank with 1 unit of vibration shaker, 1 unit of centrifugal pump, 1 unit of mud agitator, 1 ea lighting, walkway, stairs, guard rails, valves, and pipelines, etc. accessories. The vibration shaker with water spray system to prevent solids blocking of the screen. For different applications, the shaker feeding system have different options as weir feeder, top box feeder, hopper feeder. In this system the shale shaker feeding way is top box feeder through pipelines on the top. The centrifugal pump’s impeller and pump casing are made of hard ductile iron alloy for better abrasion resistance, to protect the centrifugal pump impeller and pump casing, the shale shaker should separate most of the coarse solids from the liquid and the discharged solids should be as dry as possible. The shaker screen installed on the shale shaker is composite material frame shaker screen for longer working life, especially for the slurry with high solids content. The shaker screens are produced by GN solids control and comply with API RP 13C standard, the wire mesh is made of stainless steel 316L, the frame are made of composite material for longer storage life and durable working life.

For oil &gas drilling application, there are 2 vibration modes for option, linear motion and progressive elliptical motion to meet different requirement for their drilling fluid.
For solids liquid separation application, normally we only need linear motion with high G force up to 8.0 G for better drying performance.
The further treatment equipment after shaker is decanter centrifuge with dewatering unit, to separate more fine solids from the fluids and get pure water, most of the fine solids can be separated out up to 1 micron.

Decanter Centrifuge and sludge transfer pump for Environmental Engineering Company

BY gnadmin 18 October 2020 Uncategorized

Recently GN solids control shipped one batch of decanter centrifuge with sludge transfer pump for environmental engineering company abroad, this is for non-oil & gas industry application. The equipments list including:

2 units of 9 inch bowl mini decanter centrifuges, we have 3 models for the 9 inch bowl decanter centrifuge, GNLW223D & GNLW223D-VFD, GNLW224D & GNLW224D-VFD, GNLW224EP series, the 9 inch mini centrifuge can be used for core drilling waste water treatment to recovery more water and for environmental protection. The GNLW224EP series decanter centrifuge can be widely used for different waste water treatment, we can provide customized design to archive better treatment result. The difference of these models are bowl length, back drive motor and differential speed. The longer time of the waste water stay in the clarifier section, the better of the discharged water treatment result.

Centrifugal pump, which can be used as sludge transfer pump, charging pump, feeding pump and trip pump, all the parts are interchangeable with world famous brand centrifugal pump, the pump casing and impeller are made of hard ductile iron alloy for better abrasion resistance.

Sludge vacuum pump can be used as transfer pump of different materials, like drilling fluids, drilling cuttings, animal waste, industrial waste, oil contaminated soils, sand, oil sludge, hazardous waste and others. It is 100% air operated pump without electricity power consumption, but it requires air compressor for air supply and provide pressure. We have 3 models of vacuum pump with 10m3/h 20m3/h and 40m3/h nominal flow rate for option, the actual flow rate will depends on the material density, viscosity and the suction/discharge distance & depth. The small model is movable design with wheels and the bigger model frame is fixed.
